Be it known that l. RoYCon rsu Unsinn suE 1 cf ea" .iff off. 'c1 i in and relandi at l &' il" luildinfr7 5 25A Elizabeth Street5 Sydney,. New South "Wales, Australia. have invented certain new and useful lmprovements in Cabinets for rlallrinrg-ll/lachilie-Record Die-lis.; of which the followingI is a specification.

y Chis invention relates to record dish cabinets in which the dislrs are retained in vertical compartments by means of a pivoted bar and tendto roll forward when the bar is manually operated, and has been devised to ensure rapid removal and replacement of any desired dist: without undue effort or damage to the record surface or surfaces lt has been found that inconvenience and damage to record dislrs while beine' inserted 'into or removed from the compartments are due to warping' or distortion of the partitions or walls of the compartments and to the consequent failure of the'retainingl stop or bar to act freely and quickly.

To overcome these defects l form `the partitions of reinforced fibrous material and insert between each pair of partitions portion of pivoted stop and release har which is weighted at one end and l asistI ...ie action of o'ravity on the bar by means of a. resilient rod in contact with each bar.

By the use of reinforced partitions the normal shape of the compartments is retained 1onder even excessive variations in the temperature and humidity of the atmosphere thus permittinp.` the disks to roll freely and the stop and release bars to act without extraneous friction.

The partitions may he formed of desired fibrous material such as straw-or-millboard, plv-wood. fibre-cement sheets or the like and in each case the partition is rein-- forced with metal strips. metal or wood rods. vire meshi corrugated or expanded metal. or similar stiff material secured to or within the fibrous sheet in any convenient manner. The faces of each partition are covered with a soft lining' to prevent in- 1 jurv to the record surfaces.

Each stop and release bar is approximately rectanfrular in lonrritudinal section but 'is weighted at one end and pivotally mounted so that one end normally7 projects within a compartment of the cabinet. the outer end, which is manually operable, beine' provided with a groove on which an em bossed or raised immoral. is formed corresponding', to the number of the record held within the compartment. The stop and reA lease bar 'is adapted to retain a record disk wholly within a compartment when the bar assumes its normal tilted position, butq when moved out of this position, it permits the dislr to roll forward until the disk als in contacts with the bar. The disk is thereby retained securely in this forward position with a segment of its surface projecting lieyond the face of the cabinet; from this position it may readily be removed.

The stop and release bars may be mounted across either the lower' or the upper face of the cabinet ln the latter case the weighted end of each bar will project from the compartment and a rod to retain the diseis in their proiectino' forward position will he mounted across the lower face of the cabinet.

ln the former case the retaining red is not required as each bar serves to retain dislrs in both their housed and their projectinopositions.

The top and the bottom plates l0. 1l of the cabinet are morti sed to receive partitions l2 which are suitably7 reinforced by metal strips 13 (Figs. 6 and 7l or wire mesh 13 (Figs. 8 and 9) and are covered with a soft lining not shown. Each partition may eX- tend to the back of the cabinet or to a point tlf) Bil
